7.16.6 Current imbalance warning
A warning signal will be given if the phase imbalance
between the currents is higher than the set value, The
difference in current between phases is measured in %.
Restart the motor and check the
voltage.
Current imbalance warning is configured with the
following parameters:

22.02 Over voltage trip time
22.03 Over voltage out
22.04 Over voltage
7.16.8 Under voltage warning
A warning signal will be given if the main voltage is higher
than the set warning level. Check the main voltage.
Under voltage warning is configured with the following
parameters:
Parameter
22.05 Under voltage level
22.06 Under voltage trip time
22.07 Under voltage out
22.08 Under voltage
